Nothing special about this hub - performs just like a regular usb 2.0
Unimpressed with the current product - claims to be usb 3.0 and even has the usb port colored blue, but i see no tangible difference between using computer's internal usb 2.0 port and this hub to transfer files between my computer and usb drives back and forth. Ran a few tests, used usb 3.0 thumb drive to copy several gb of pictures and videos first thru kingwin hub and then thru the computer's internal usb - surprisingly, it was literally the same amount of time. No extra programs were running on the pc to somehow affect either test. It's just convenient to have 4 usb ports in place of one, only reason it got 3 stars.
